A. Humberto Castillejos is a Professor of metallurgical engineering at the Centre for Research and Advanced Studies, CINVESTAV, Unidad Saltillo, in Mexico. His teaching responsibilities include graduate level courses in transport phenomena and computational fluid dynamics in metallurgical engineering. He did his B.S. degree at the National Autonomous University of Mexico, his M.S. degree at the Imperial College of Science and Technology, UK, and his Ph.D. degree at the University of British Columbia, BC, Canada. His research interest is in process metallurgy, where he works developing physical and mathematical models to represent the transport phenomena involved in different processes. He has specific expertise in developing models for processes such as ladle metallurgy, ferromanganese production, filtration of aluminum, ceramic filter design, anode design of DC electric arc furnaces, secondary cooling of thin steel slabs, and Pachuca tanks design. At the present, his particular interest is the fluid dynamics and heat transfer involved in spray cooling of highly superheated surfaces. Liaisons and collaborations have been developed, nurtured, and maintained through consulting and research projects with selected industrial partners. Long-term, mutually beneficial collaboration has been built with Hylsa S.A. de C.V. (now Ternium México), a leading Mexican steel manufacturer, with which applied research projects have been undertaken and completed successfully on the analysis of ladle pouring temperatures, DC furnace anode design, optimization of secondary cooling strategies in thin slab casting, and characterization of surface defects in continuously cast thin slabs. He developed and built a permeameter to characterize the flow resistance of ceramic filters for metal cleaning for FOSECO Inc. and conducted industrial trials and modeling work that led to the development of a refining process for producing low-carbon (= 0.5%), low-nitrogen (= 400 ppm) FeMn, for Minera Autlán S.A. de C.V.
